A measurement of the quality of vegetation zones in dynamic terms is provided by the Fourier analysis of time series of AVHRR/NDVI monthly observations over ten years. The present approach is shown to be a powerful way to classify and extract various dynamic parameters of the vegetation in Southern Africa. The resulting map of isogrowth zones of Southern Africa was highly correlated to a radiational index of dryness or Budyko ratio, as well as to the spatial distribution of vegetation types accordingto White.
